Platform Conventions: iOS, Android, and the Web
Each major platform has developed its own established interaction conventions over years of real use, and a design that ignores these established conventions in favor of an entirely custom pattern imposes a genuine, avoidable learning cost on every user already familiar with their platform's existing expectations.
A specific interaction pattern, a particular gesture, a particular navigation structure, becomes an established platform convention specifically because a large number of other products on that same platform already use it consistently, meaning a genuinely large share of a platform's users have already learned that specific pattern through their broader, cumulative experience across many other products, not exclusively through any single product they happen to be currently using.
- Platform conventions become established because a large share of users have already learned them through cumulative experience across many other products on the same platform.
- Deviating from an established convention purely for visual distinctiveness imposes a genuine learning cost that should be weighed honestly against the actual benefit the deviation provides.
- Deviation can be worthwhile when a product's core function genuinely requires a different pattern a standard convention can't support, but this should be a deliberate, considered choice.
- A product that does deviate should still maintain internal consistency in applying that deviation throughout its own interface, avoiding a second cost of unpredictable behavior.
